According to the Google Adwords tool, "stack overflow" is googled 74,000 times each month. Not to mention all the permutations. If I worked for Stack Overflow, I would also try to optimize for more general terms. The questions and answers are good at getting those long-tail keywords, but not so good at the more generic ones like "coding help" or "javascript help" or a hundred others. Stack Overflow isn't on the first page for either of those examples, or many others.
